Re: Infrequent disk system hang on 5.4-RELEASE-p8

(OK, I'm *waaay* behind on -hackers.)

In  [EMAIL PROTECTED] you write:
We have an older server, running 5.4-RELEASE-p8 and used primarily
for email, which hangs every couple of weeks.  The hang seems to
be in the disk I/O system.  Based on the times of the hangs, the
triggering event seems to be running dump.

We have a serial console set up, I broke to the debugger and got the 
following.  Since the hang is in the disk I/O system, a dump is not
possible.  The many versions of inetd are likely due to users attempting
to POP their email.

Any suggestions or tips on how to track this down and get it resolved
would be appreciated.

This looks very much like a bug I ran across a while ago.  Look for
snapshots and innds in the subject line.

It doesn't seem like this has been resolved.  You may slap my
hand for not filing a bug report previously; I'm about to do
that.

The solution, so far, seems to be upgrade to 6.x.  Whee.
